First thing is we need to practice a lot. After practicing we need to find our own algorithm which does the same in lesser time then there comes a technique.
How we move pieces is also important. To solve Rubik’s cube in lesser than 5 seconds we need to have flexible cube.

By having a feel for what a move does to pieces that we aren’t focusing on, we can decide which moves will lead to an easier algorithm after, and know which move to do next rather than needing to look again.
It's known as look-ahead. And this means we can choose a slightly longer algorithm to save ourself from an even longer one afterwards, or even extra stages.
Speedcubers get so fast because they're using advanced methods. Generally, the two main ones are CFOP, the most popular, and Roux.
CFOP is considered to be faster, though. It goes through four (4) steps, the intials of those four-steps give the method its name.
First, we build a cross. Not to hard to do, even a beginner could do it.
Next, we build the first 2-layers. This is done by paring up corners with edges, then inserting them into their correct spot.
After, we orientate the last-layer. This has to main ways to do it, in 1 (one) algortihm, or by building a cross, then orientating.
Finally, we permute the last-layer. Like OLL, this can be done two (2) ways. The first is by permuting the corners, then the edges. The other, more advanced way is to do it all in 1-algorithm.
Once we got this down, it's not to difficult to get sub-30 solves.

Memorization
In order to solve a rubix cube, we memorize a set of moves or algorithms that can be applied broadly to many situations to move pieces from one place to another (without disturbing other pieces).Once these basic algorithms have been mastered, we can move on to memorizing more specialized and efficient moves that won't get utilized as often, but cut out unnecessary steps.
Eventually we get to the place where we can solve the entire cube based on the starting configuration, without looking after we've started; at which point, it's a matter of dexterity.
